Chapter 9, Problem 34(choose chapter or problem)
(a) Three carts of masses m1 5 4.00 kg, m2 5 10.0 kg, and m3 5 3.00 kg move on a frictionless, horizontal track with speeds of v1 5 5.00 m/s to the right, v2 5 3.00 m/s to the right, and v3 5 4.00 m/s to the left as shown in Figure P9.34. Velcro couplers make the carts stick together after colliding. Find the final velocity of the train of three carts. (b) What If? Does your answer in part (a) require that all the carts collide and stick together at the same moment? What if they collide in a different order?
